My warm water rods are assembled all season in a hot shed. Trout rods would, too, but I don't trout fish much around home, so drive to the MT cabin with those in the tubes, then assemble and transport as follows for a week or 3 months.
I used to transport in a Thule rooftop box, leave them up there overnight, etc. still would, but back in a 4runner again (roll down rear hatch window) and an AWD full size van.
My in-vehicle system is a homemade rod suspension up close to the vehicle headliner with closet rods and bungees. I back away from the shed with 2 in each hand, or grab them off the nails in the front wall of the cabin, bear dance around the trailer tongue - often with a dirt bike for the shuttle on the receiver hitch - poke them into seat backs and headliners, finally get them suspended, from the fighting butts and the last foot of rod, and they will ride there for a half hour or three weeks.
I have a rod broken once or twice a year, always by an angler doing some thing stupid. I have 15 year old sage rods that have spent their lives this way, and they work great right up until somebody slams them in a door. I would never do this with bamboo, but a big reason for that is that I don't own bamboo, because I couldn't do this with it.
